storage/posix: log the error when locking the export directory fails
posix xlator tries to prevent external unmount of the brick export directory by locking it. It locks the export directory by opening it (i.e. doing a opendir). But if opendir fails it errors out resulting in the brick process going down. The error due to which opendir failed is not logged.
